How is the online monitoring system for drainage pipe networks?

　　 Online Monitoring of Drainage Networks The system employs low-power remote monitoring terminals and other devices to collect real-time data on rainfall, water levels, flow volume, flow velocity, water quality, and concentrations of toxic and hazardous gases, enabling information-based management, urban drainage emergency response, comprehensive automated control of large pumping stations, and water resource management, among other functions. This data is aggregated and transmitted via a wireless network. Let’s take a closer look at what the online monitoring system for drainage networks has to offer!

　　Providing foundational monitoring data for “Sponge Cities,” the online monitoring system for drainage networks serves as a critical component of Sponge City development, enabling a shift toward dynamic, refined, quantitative, and scientifically informed management, thereby substantially enhancing the overall capacity and sophistication of water‑resources administration.

　　Components of the Online Monitoring System for Drainage Networks

　　1. Sensor monitoring layer: Primarily composed of various monitoring sensors, including those for rainfall, water level, flow rate, gas, and water quality.

　　Detailed Description of the Functions of the Online Monitoring System for Drainage Networks:

　　By measuring the Doppler frequency shift of acoustic waves scattered by moving particles in a fluid, the fluid’s velocity can be determined. Doppler ultrasonic flowmeters exploit the Doppler effect of sound propagation in fluids and, when combined with an integrated pressure‑type water level sensor, enable flow measurement using the velocity‑area method. They are suitable for measuring flow velocity and discharge in open channels, riverbeds, and situations where constructing standard cross‑sections is challenging, as well as for measuring flow velocity and discharge in both full‑and partially‑filled open channels.

　　Features of Online Monitoring Products for Drainage Networks

　　It employs a design that integrates all functions, simultaneously measuring average flow velocity, water depth, and water temperature.

　　The velocity‑area method is employed, with no head loss and no need to construct a standard flume.

　　It offers high measurement accuracy and low start-up velocity when measuring flow velocity and flow rate using the ultrasonic Doppler principle.

　　Without a mechanical rotor, it does not disturb the flow of water and enables more accurate measurements.

　　It is equipped with a temperature sensor to compensate for the effect of water temperature on the speed of sound.

　　It can measure both instantaneous flow rate and cumulative flow.

　　Employing a frequency-domain Doppler analysis algorithm, the system delivers stable data with high reliability and excellent real-time performance.

　　The online monitoring system for drainage networks is easy to install and requires no auxiliary infrastructure.

　　Applications of Online Monitoring Products for Drainage Networks

　　Flow measurement in various full‑pipe and non‑full‑pipe scenarios, including waterways, river channels, sewers, and drainage networks.
